3.Mica's main advantages are insulativity and heat resistance, which are perfect:
1). If mica's thickness reaches 0.015mm, its average breakdown voltage would be 2.0—5.7kV, puncture strength would be 133- 407KV/mm.
2). When mica is heated by temperature of 100-600°C, its elasticity and surface properties will not change.
4.Main Application:
(1) Used in decorating, paint and coating.
(2) Mica powder is the basic raw material for mica ceramics products.
(3) It can be used in fire-fighting dry powder, protecting layer of welding rods, conducting wires and electric cables.
(4)It can be taken as a filler, shelter, lubricating substance, drawing of patterns in plastics, rubber, asbestos products and sealing materials. It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products. It can be used as coating in models of forcasting metal, the brightening material in aluminium and paint in electroplating bath.
